Nail Driving Force - Hitachi NV 45AC Technical Data And Service Manual

5-3. Nail Driving Force

Fig. 2 shows by type of wood and nail the nailer output energy provided by the supply pressure and the nailing
energy required for driving the nail flush. Air pressure which exceeds the intersecting point between the nailer
output energy and the required nailing energy for driving the nail allows the nail to be fully driven.
For example, when driving a nail of 3.05 mm dia. x 45 mm length (0.120" x 1-3/4") into a workpiece of hemlock
with the Model NV 45AC, a pressure of about 6.9 bar (7 kgf/cm
with the wood surface. A pressure beyond this value causes the nail head to be driven below the wood surface.
Fig. 2 should be used as a reference only because those values vary depending on the type of wood, moisture
content, and grain of wood.
